Crash Bar Caught On Fire. Too Old, Or Poor Decision?

Due to other security issues, I set one of my doors to permanently unlock. It's a Precision electrified crash bar. An hour later, smoke was pouring out of it and it was too hot to touch. Facilities tore it open and cut the power wires (I was not available).

My question is, did the crash bar smoke because it's 20+ years old, or did I ask too much of it by keeping it energized in the unlock position?
